Much has been written about the prosecutorial prowess of Robert Mueller's team assembled to investigate allegations of Russia's involvement in the Trump campaign. Little has been said of the danger of prosecutorial overreach and the truehistory of Mueller's lead prosecutor.

What was supposed to have been a search for Russia's cyberspace intrusions into our electoral politics has morphed into a malevolent mission targeting friends, family and colleagues of the president. The Mueller investigation has become an all-out assault to find crimes to pin on them -- and it won't matter if there are no crimes to be found. This team can make some.

Many Americans despise President Trump and anyone associated with him. Yet turning our system of justice into a political weapon is a danger we must guard against.

Think back to April 1, 1940, and a world awash in turmoil, hate and fear. Revered Attorney General Robert H. Jackson assembled the United States attorneys. In remarks enshrined in the hearts of all good prosecutors, he said, "the citizen's safety lies in the prosecutor who tempers zeal with human kindness, who seeks truth and not victims, who serves the law and not factional purposes, and who approaches his task with humility."

Yet Mueller tapped a different sort of prosecutor to lead his investigation -- his long-time friend and former counsel, Andrew Weissmann. He is not just a "tough" prosecutor. Time after time, courts have reversed Weissmann's most touted "victories" for his tactics. This is hardly the stuff of a hero in the law.
